Cannot thank you enough for walking through the various components of the PCV system. This allowed me to properly diagnose and repair the PCV system. It also saved me from spending additional money on the intake manifold that wasn’t needed…yet. I did need to run the car for quite a while (at least 30 minutes) after the repair to get all of the accumulated oil in the intake manifold driven out. I was overjoyed when the last bit of blue smoke stopped and the little engine got back to normal. She purrs like a kitten and pulls right up the hills better than she has for a while.
That’s so awesome to hear! Very glad that you were able to sue this information and get your car fixed. That’s been the goal behind everything I’ve done here. Saving people time, money, and frustration.
Hands down, Andrei creates the best DIY repair tutorials for the Chevy Cruze. His step-by-step instruction guides include pics, which virtually eliminates the need to take pics as you go along (although I recommend you do anyway). And his work-around kit for the POS OEM PCV system is ingenious and affordably priced. I feel like I owe him more money for making this so simple and affordable. Thanks, Andrei.
@@AndreiDPop to be fair, I just pulled the manifold yesterday. I will install the fix to it with your kit today. But what pain in the ass it was to pull the manifold!
I spent countless hours trying stop the oil leak from around the valve cover. Saw your video, ordered the intake manifold and installed it. No more leaks!!! Thank you so much for taking the time to make the video. Truly helped. Now I’m searching how to remove oil stains from driveway..lol. Thanks again!!
This is one of the only videos on TH-cam that explains and fixes the problem correctly. I can't believe how many other video of "mechanics" not correctly fixing this problem. Thank you for all you have done for us fellow Cruze members. I will be buying your newest pcv fix kit. Thanks again
Man I wish more mechanics were as knowledgeable as you appear to be. Would have saved me loads of money over the years. I’ve found TH-cam and doing it yourself saves time and money and even the hassle. Thanks for sharing your knowledge. Subscribed and liked
I have been a Technician and do many other repair jobs for me and others. Save Soooooooo much money MOST of the time. Some time tools can be a "paywall", some times it's just a skill set you're not that good at. I don't do carpet or drywall; I will help do tile, not on my own. lol Live and learn. Still, learn everything you can, and try anything!!
You are so great!!! A lot of people out there totally have no idea about that "vacum control membrane" and they call it PCV valve.. Actually i'm a physician but i have interest in automotive. I have 2008 chevrolet captiva and i dissasembly that "the so called pcv valve" and totally confuse about the name of "positive crankcase valve" becoz on that valve construction i bet it is not regulated by positive pressure, but the valve/membrane will actually move by negative pressure. Then i found your video and you make it very clear that it actually a vacum control membrane!!! Thanks again 👍👍👍
Hi, thanks for inventing the kit. I just bought a 2011 Chevy Cruze Eco and ordered your kit already. I hope it works well because I want to make this car my daily driver.
Thank you for having an explanation for this. I’ve been troubleshooting for months for a “squeaky noise” from my engine bay. Finally figured it out. Thank you again!
That's a brilliant explanation, and your website explains it even better. I find it frustrating that mechanics don't think first about how these systems work, since understanding is necessary before one has any hope of fixing things properly. Matching blowby gas flow through a PCV with the dramatically variable intake vacuum of a turbo is a huge challenge. So, I guess we shouldn't be surprised this system is much more complex than a simple captive ball and spring.
Just wanted to give a big shout out "Thank you!" as I had several codes - everything you'd mentioned in your video! I was on the fence about selling my 2014 Chevy Cruze LT and finding one error after another pop up, but since it's paid for, I thought why not see about fix it permanently? And so, I came across your video and purchased your "GM 1.4L LUV/LUJ PCV Fix Kit V2" - kind of a h*ly sh*t moment after firing it up and running it with your kit on! It now runs like it did when I drove it off the dealership parking lot! Wow - just wow! Dre Dan's kit was the perfect fix for all my problems so at the very least, I thought I'd write you and again, say thank you! For a 100% failure rated part, the intake manifold with it's cheaply designed check valve...well, this is the way! It was also a good time to clean the throttle body and everything I had access to - a lot of built up crud as this was the first time having it apart since I bought it. This was surprisingly an easy job and your kit came with everything you need - was fun actually! Dre Dan, so glad I purchased your kit!
Thanks for the awesome review! I really appreciate it. I'm so glad this fixed your issue. It's great seeing feedback like yours. I really appreciate it!
Thank you Dre Dan! I was leaking oil from the throttle body on 2012 cruze lt. Didn't see a nipple after removing corrugated hose. Sure enough the orange check valve was missing after taking the intake manifold off. Huuuge thanks for all the info on cruzetalk and here.
Ya my 2015 cruze lt is leaking oil from the intercooler charge pipe connected to the throttle body, i was wondering if i shoukd take the manifold off and take a look but its my everyday car so its abit hard to check at the moment
Thank you, you just save me over $500 my encore has hissing so it’s only value cover replacement, greatly appreciate you posting this video and I will buy that kit you make if manifold ever fails.
Keep in mind, simply seeing the check valve in the intake manifold doesn't mean it's working. Very recently, I had a friend install my kit which meant pushing the check valve out and catching it on the other side to plug it up with my kit. Turns out his had a tear in it, and it wasn't during removal. For many people, the check valve either gets stuck closed or even caked with deposits and starts leaking. Waiting for it to fail can often cause other issues down the road due to oil consumption. If you have over 30k miles on the intake manifold, I recommend not waiting until it fails.
@@AndreiDPop Well, I have only changed the intake manifold once on my Cruze and I have 306,464 miles now. The valve cover has been changed 3 times. But sadly my turbocharger is starting to fail. Wastegate is locking up. This is the original turbo and has lasted over 300,000 miles.
@@AndreiDPop Bingo! I would say 90% of the miles are highway driving. Drive over 30,000 miles a year. I have owned the car since January 2011. I've been good to this car and I think I got my money's worth. One last note, I never used air conditioning, no matter how hot it was. It seemed to affect the car early on. So, I decided to not use it.
@@AndreiDPop "Keep in mind, simply seeing the check valve in the intake manifold doesn't mean it's working." ... - This point cannot be stressed enough. I'm from the UK & work primarily on Vauxhall, a brand of GM, using the same systems; all are terribly designed. The intake manifold PCV non-return / check valves can indeed tear or become clogged "open" with carbonised / burnt oil deposits; symptoms are mainly observable with positive manifold pressure, ie. "boost". Faults with this valve will cause consequential faults with many other components.
Thanks for the help so I can tell my mechanic I did research on these Pcv valves cause I had a really bad rough idle even after cleaning the throttle body with no codes unfortunately I checked the Pcv valve in the intake manifold and it’s all gunked up can’t even see where the nipple is so I’m gonna have him replace that with the Pcv valve cover as well and hopefully that fixes it. Just taking extra precautions and having home fix those even after the diagnosis and whatever else he finds needs to be replaced or repaired.
Your video talked about the other end of the PCV hose at the turbo and a check valve there. Does that one go bad and ever need replaced? Next question: If the valve cover gasket goes bad, does this create a vacuum leak and cause poor performance? My Cruze gets random lifter noise that comes and goes. I checked the valve on the valve cover, but it wasn't blowing air. I replaced the valve cover gasket because it was leaking oil. Since then, I've had no issues.
Yes, the check valve on the other end of the PCV hose sometimes goes bad, and creates a vacuum leak. We find it gets stuck open more than it does get stuck closed. Yes, a bad valve cover gasket can cause a vacuum leak. Check spark plugs, as they sometimes back out. Lifters shouldn't make any noise unless you've been using low quality oil.
Nice bypass filter system, is it Amsoil? I put one on my 2.4l Ecotec. It returns directly onto the timing chain, keeping it bathed in clean oil, no more GDI soot. I also did an external PCV system. After 100k miles, engine is extremely clean, no varnish, sludge, even 10-12k intervals.
Yes it’s an AMSOIL single remote bypass. Not really much benefit outside of adding an extra quart of oil capacity but it was a fun project. I took it off last year after using it for 8 years due to the cost of filter changes.
@AndreiDPop really, no benefit? How do you come to that conclusion. Being an Amsoil dealer, I thought you would understand the benefit. I stopped using PI, Engine Flush, Power Foam, did nothing to help. Still use Metal Protector.
@@tssci6774 soot and insoluble contamination isn’t a concern with gasoline engines. That’s why you only ever see bypass filters where soot levels are measurable. I ran a case study with AMSOIL in a focus ST where we did 13 oil analysis reports and 50,000 miles on two EAO filters. Lab said oil was suitable for continued use and there was no soot measured. I did another case study with a Cruze turbo diesel that went 100k miles on AMSOIL AEL and soot wasn’t an issue with that engine either. So if soot isn’t an issue and wear is at acceptable rates, what benefit is the bypass filter offering? On paper yes I could say beta75 at 2 microns is great filtration but at the end of the day is it consequential? In my opinion it isn’t.
I heard this today. "Vehicles nowadays can surf the web, stream videos, navigate and pinpoint a location in a map, but can't tell you why their check engine light is on." How ironic is that?
Hello, and thanks much for this video and the kit you've designed... i will likely be ordering one of those shortly. My girlfriend has a Cruze, and the diaphragm on the valve cover is indeed failed and leaking vacuum.... it also sometimes makes a whostling sound that sounds like a belt squeal... when you plug the vent of the diaphragm on the valce cover it immediately makes this sound. I've diagnosed this to be vacuum leaking , and sucking air in around the crank seal. I am thinking that adding your kit, as well as a new valve cover, and possibly the hose and valve by the turbo inlet, will ALL be necessary, but I also think we should be replacing the crank seal as well....she will likely keep the car, or eventually give it to one of her kids , so I want to fix it right... Any further input or suggestions would be most appreciated. Thanks again for doing us all the service of making this video, and designing a kit to provide a metter solution than OEM part replacement....
Even after all that, you really think this thing will last? Haven't talked to or seen anyone saying these are cars that can be depended on to last without giant headaches every few years
I had same issue with a sonic. only when i covered the diaphragm hole it started directing oil into the intake and then the car started smoking from the tailpipe like crazy. Thanks for the info will be ordering kits from you.
Dear Dre Dan, Thanks for your great videos, explanation and kits avaliable to get - it's great solution for this strange crankcase ventilation system from GM with this PCV Mushroom valve in the intake manifold at A14NET engine and similar. I wonder to know, why they don't use the same system which used at A16LET engine, where the PCV valve made externally, almost exactly how you made at your kits? It's rhetoric question ;) But what I really wonder to know and can't find relevant information concerning this issue - what if the ventilation system will only one way. I mean, if the mushroom valve hole will be plugged up in the intake manifold and only way of ventilation will be via corrugated hose to the the turbo charger. Such way will be completely identical to the default ventilation system during the boosted, loaded mode. But what will happen at the idle mode or mode with little load ? I suppose, that if it will be not enough air at the intake manifold for the stable engine operation the electronics will open the throttle valve a bit more to provide the enough air flow. Further the more air will be sucked from the turbo charger and from the corrugated hose connected to turbo inlet - so the crankcase ventilation will take place in this case as well. I am not completely confident in my thoughts concerning this crankcase ventilation as I am not specialist in it, but why double-way ventilation system needed, what is the benefit of it? Best, Igor
Wow thank you Igor. You just gave a great explanation of what is most likely going on with my vehicle. Now just need to buy a kit and see if I can find the root of the problem. Thank you man
@@franklujan7480 Hey Frank - btw I don't own Astra anymore, but I was able to fix it with the way described with "self-made kit" and after fix had another ~20k km successfully. Best of luck!
Dre Dan, Thanks for the video! Great explanation on the system. I have an oil leak somewhere between the charge line and throttlebody. Have you heard of this before?
@@AndreiDPop Am I reading this correctly? Are you implying that some oil leaking from the charge pipe is acceptable? A lose clamp? Wouldnt this be a check valve issue, resolved with a DRY charge pipe yes?
@@ripptydevibes2581 If you have oil leaking form the charge pipe, you also have a boost leak there as well. Some oil will come through the PCV system, but it tends to settle in front of the throttle body and leak at that charge pipe, even if actual consumption is inconsequential. Even a healthy car will consume some oil through the PCV system, and some of that will find its way through the intercooler and up the charge pipes. Not something to worry about unless oil consumption increases significantly. A check valve issue will make it *worse* but a minor amount of oil will still go through the charge pipe on a healthy engine.
@@AndreiDPop Agreed, thanks for the quick reply. I guess we arent as used to seeing oil at the intake on natural aspiration, but owning my 98 mitsu 2.0l running 32psi, it was nice of you to remind me that it is somewhat normal for the Chevy Cruze to have oil in its charge pipe lol. This customer is missing the check valve nipple, and im considering pricing your deletion kit and valve cover job, but shes already been in deep with this cruze at 100k miles so im almost as likely to start washing my hands of it and let someone else grow into the bad guy lol. Shes complaining of the heater vent smells and ive already rerouted her coolant breather to under the frame, gonna tell her take it to chevy for that but then theyre gonna hammer her with a list of reasons and $2000 in repairs that likely wont do anything! Thanks again!!
@@ripptydevibes2581 the v2.1 kit should keep her PCV problems at bay. It's not a deletion kit but a re-route with serviceable components. I also have installer pricing at 15% off if you want to go this route.
@@AndreiDPop how can I order the PCV Kit from you? Also, I have not done a turbo boost leak test as I would like to get my hands on one of those as well.
Hey buddy, I recently installed a new intake manifold and valve cover before finding your kit, could you possibly explain too me where the bypass hose coming from the turbo is connected too? Specifically on the engine side? I have mine connected where the turbo is but I can’t for the life of me find out where the other end goes ( I believe this is creating another vacuum leak) that being said if this fails again (which is likely) I will be purchasing your kit. Thank you!
Literally I was looking at the broken end of that corrugated hose in my hand thinking "wow that was smart" and in my Bluetooth headset I hear "now be careful just gets brittle over time". F this day.
Ha ha F this day ...... sometimes I think all this S*** only happens to me and i'm the red headed step child of the world but I realize I have siblings in this S***....
I'd love my sonic if it didnt have issues. But I've had nothing but problems with mine. Just spent 2400 dollars on repairs just for the light to turn back on less than a month later.
Code 299- turbo cracked, valve cover regulator leaking and most likely the pvc check valves- Do them all together! And get new oil return line with turbo.
Chevy again 😒🤦🏾♂️ good concept but poor design.. if they had only made it non-integrated then it could be easily replaced.. good work around thou 😎💢👍🏾
Currently working to be ridd of my 2015 Cruz LT, less than 97,400 miles and still under warranty but constantly denied any warranty coverage. Also, learned yesterday when the mechanic was on the phone with the warranty department, this car was sold to me without informing me of the recall that is ongoing. It's sitting in my driveway after being towed home yesterday because I refuse to sink another penny in this money pit. As of last week, I've had the pos 20 months; its broke down a 4th time. And this time, the issue is the same as the first time it broke down. JUNK!
what is the other hose that's tapped into the valve cover opposite side of the oil fill cap? also are you not running the factory style coil anymore? i see you have 4 sperate spark plug cables there.
@@brandoncatanzarite8729 that’s an AMSOIL single remote bypass filter return line. I’m running badnewsracing.net LS7 coils to support the badnewsracing upgraded GTX turbo.
Dre Dan As opposed to my new 17 Civic, the new Cruze has five more inches of leg room, better seat angles and comfort, less road noise, more torque, better styling, and music/infotainment/sat radio. But, its the reliability and clutch engagement that concerned me. I wish I had the Cruze for the comfort. You cant have it all.
Can an issue left unresolved in the intake manifold cause issues with the diaphragm? I’d previously replaced the diaphragm when my check engine light had come and I felt the vacuum issue out of the diaphragm hole on the valve cover, but only recently installed your v3.4 pcv fix kit when I was starting to have rpm issues idling and those issues are persisting even after your kit was installed, though no check engine light yet
Yes and it happens often. With the intake manifold malfunctioning or failing, the valve cover will fail prematurely, even 5x more often. Sounds like you have a vacuum leak, so you’ll need to find and address that.
Do you have another video on how to put your kit and how to purchase it.I also have a 2012 cruze and the orange nipple is gone and that has to be the problem of the car shaking like it has a vacuum problem.
There’s a video for the v3 install and there’s downloadable paper instructions on the cruzekits site for the v1 and v2.1. Most people order the newest v3.4 kit as that’s the easiest to install. Be sure to read the note sheet!
I just used the boost leak test kit. The only leak I had was throught the valve cover gasket. Could that be because the PCV it shot? I have a sonic I can't look down the PCV hose inlet.
Thanks for posting this. I have a 2013 Volt, which has the same engine just without the turbo. It wouldn't pass emissions nor would it set a check engine light. It was running just lean enough to not set O2 sensor readiness nor was it lean enough to set a check engine light because of the same exact leak in the valve cover.
With the kit installed, you should need a catch can at all. However, the v3 turbo may create conditions that create a need for a catch can so I can't say if you'll need one then.
@@paceauto5382 make a note in the kit when you order it so I can get you the T fitting you'll need for the catch can setup. The fitting currently used wouldn't be very good for adding a catch can.
Great, easy to follow explaination of this system. P1101 does not go away on my car. The dealership replaced the turbo with new gaskets the first time. The second time they found a vacuum leak on the camshaft cover, third time came up after my battery died, and now I'm so fed up with this code! 4th time, all within 8K miles. Best part is, the code comes and goes as it pleases. I'm going to take matters into my own hands and replace the pvc hose to the turbo. Any other suggestions?
Map chip. It happened with my woman's 2015 sonic they changed 4 sensors and still same issue so the dealer called factory tec. And it was the map was going out.
I’m getting oil into that PCV tube, and I’m pretty sure it’s coming from the PCV valve in the intake manifold. If the PCV valve is bad it will let oil in?
So if I'm getting suction from that diaphragm on top and also don't have a nipple for the check valve, do I need to replace/repair both?.....I've also got a bad front crankshaft seal that I'll have to replace due to the squeaking noise.
I bought the dorman intake manifold and also the valve conver, the car now started acting weird and its leaking oil from the valve cover. I took it to the mechanic and he inspected it for a couple hours , replaced the pvc hose, the map sensor, the intake manifold sensor and still the same problem. He says that the engine is not receiving the needed air. What could possibly be the issue? Thank you
Hello, can you please reply, I need your help. The orange nipple, that is, the check valve, in the intake manifold of my car is completely missing. I would seal this place without a repair kit (Cruze kits) with any material and epoxy adhesive, and use the original crank ventilation hoses. Is there any problem if I continue to use it? Please reply, it's urgent.
Ive had the kit V3 kit on my 2014 Cruze 1.4 for about over a month or so. Have not had any issues. The crank pulley whistle, the PCV air inlet suction, rough idling, hesitation, check engine light, all have gone away and have not come back once. I did not replace the valve cover, I did not replace the intake manifold.
Does that corrugated tube have a barb on the end cause was wondering if you could just replace that with a normal rubber line and put a inline check valve in cause I did something similar on a vxr for a hard brake booster line using stronger vacuum rubber lines of course saves me from drilling the intake manifold
what you’re trying to do won’t work at all. Yes it has a barbed end and he’s you can use a PCV hose but no you can’t just run any inline check valve anywhere and especially not in the 5/8 line because there’s already one there. The v3.4 pcv fix kit does not require drilling or removal of the intake manifold.
I wiped out the area but there's no round orange tip but there's something raised up but looks like flat and black in color. It's hard to tell without taking the intake out. Is that check valve round or flat? I am getting P0299, the car is under power, the line/hose from intake to turbo has some oil and my air intake connection at the line coming from intercooler is soaked with oil. I am trying to figure out the problem before replacing parts. I just installed a brand new Chevy valve cover.
Your check valve is gone. You need to install one of my pcv fix kits. That should address your p0299 and restore some power and fuel economy and reduce the oil consumption.
Is the valve cover gasket replaceable? Fixed a p0299 with a clip missing of the wastegate/disconnected. Now I have an oil leak. Replace the big hose with the two check valves because it broke when checking the little valve in the intake. Any thoughts would be great if you have the time. The oil leak wasn’t present prior to fixing the turbo clip. Thanks in advance.
Hello Dre Dan, i have a strange noise in my opel corsa with 1.4 turbo motor from 2014(its the same motor as in the cruze), when its warm an its no belt driven part - i checked it without the belt. I checked the PCV valve to the turbo, its switching when i blow in an suck there and i can see the nipple in the intake and the valve cover isnt sucking air. But i have the simmer ring squeeking when i shut off the engine and a noise like a sqeaking belt when its warm. Is it possible to have a higher underpressure on the enginge caused by the valve cover? I first want to change the simmerring but if its not the solution for it i maybe want to change the valve cover. What do you think? The next step could be an expensive change of the timing chain. Sorry for my bad english ;)
16 Encore.. Was getting a Underboost code for a while, and i had an oil leak at the oil filter housing.. I replaced the Housing plus the turbo and now the car is misfiring and blowing white smoke.. what could this be?
Mine looks like yours, when you buy replacement valve cover it shows on the paper that part of the manifold but the circles around have orange. Ours only have the center nipple. Wouldn’t that be an issue as well ?
@@AndreiDPop thank u sir much appriciated i had guy giving me the run around wanted me to change coil packs boost sensors but i kbow thats not the issue theres backpressure creating somewere for the oil to be seeping threw the front head gasket pvc issue again im going to check thank u sir
I have what seems to be an engine oil leak on the right of the engine, coming from the lower hose by the temp housing unit. I also notice that one of the torque screws on my valve cover is constantly dirtier than the rest. This is the one on the front left of the valve cover. What can this mean? Basically my 1.4 turbo isnt producing enough power to run my AC on hot days. The AC works fine, but after 20 mins of running the car sometimes doesnt start up. Any ideas of leads of what I should check? thank you!
So it is normal air suction through oil cap when is in idle? My intake manifold has the orange nipple and new valve cover, i still have some suction through oil cap, car runs good no check engine lights , just wondering if is norma air suction???
Hi Dre Dan. I just bought a sonic with 1.4l turbo. The vacuum regulator is leaking oil from there. Do you think it has to do with the pcv valves? Any help, I'll priciate.
@@aldonoviaviles6250 you’ll need a new OEM valve cover. You can get those from the dealer but I also offer them on the cruzekits.com site. Have you checked the intake manifold yet?
@AndreiDPop so I have replaced all ready the valve cover with zzperformence. The old one was bad due to an air leak at the regulator. After a put the new one 2 weeks later, I noticed that it is leaking oil. I call the zzperfomence for the warranty and they are tell me that it couldn't be the the regulator. And I haven't check the intake manifold yet. Can you send a link to the repair kit?
Will your PCV kit extend the life of the vacuum regulator diaphragm in the crank case cover / i.e. does a missing PCV in the intake manifold damage the diaphragm? I'm at about 98,000 miles and I'm on my 3rd crank case cover. I just installed your V3 kit and the car seems to be running well. When I give it gas, it no longer hesitates - i.e. feels like more acceleration power. So far .. so good.
In my observation and experience, yes. I've had reports of people replacing 8 valve covers over a 2-year period, not realizing that their intake manifold check valve went bad. Others would install my pcv fix kit and get over 65k miles on a single valve cover. I think what's happening is that the missing intake manifold check valve introduces such a high volume of boost into the PCV system that, combined with the blow gas produced by the engine, exceeds the flow capacity of the turbo side pcv pipe check valve and pressurizes the crankcase as a result. This then causes the diaphragm in the valve cover to flex in the opposite direction than it was designed to, which causes premature failure over time. Maintaining a healthy PCV system would then resolve this issue, and the valve cover would only fail in the event that the diaphragm becomes brittle enough due to normal operation that it cracks on its own. Your experience is consistent with others that have had this issue, reporting better power and no more hesitation. You should also notice an increase in fuel economy.
@@AndreiDPop that's good news. I'm on my 3rd valve cover - replaced it 2 days ago and installed your V3 kit earlier today after it arrived in the mail. I definitely notice a difference when I took it on it's first drive. The dealership replaced the cover the 1st time, then about a year after that, the turbo charger failed and had to be replaced - thankfully it was still covered under the drive train warrantee. Could the missing PCV have played a role in the Turbo Charger failure?
Thanks for your response. I have a 2015 Buick Encore with the 1.4 L turbo. My turbo went out with the P0299 code. It took three replacements to correct the problem. The first two broke again . I was told the intake manifold needed to be replaced due to a clogged PCV, and that's why the turbos kept failing. I asked them to replace the valve cover and PCV hose at the same time (Dorman kit). I know you offer a fix kit on your website also. I no sooner left the shop after repairs, when the CEL was back again with a P0420 code. Ugh!! They did an eval and now said the catalytic converter is bad. What is the likelihood of that occurring right after the other repairs were done? The car seems to be running fine. If I clear the code, I can drive for hours at high speeds on the freeway without the CEL reappearing. It comes back with city driving. Why? @@AndreiDPop
Would this cause white smoke out the exhaust as well? I've got the p0171 p0106 p1101 codes and the disc thing on top of the valve cover is indeed sucking air and I cant see the orange nipple in the intake manifold. I wasn't concerned about it until I noticed it's white smoking but it doesn't smell like oil or coolant. Just smells like regular exhaust fumes but is thick white clouds when first starting up then it eases off a little.
The Dr is in!! My man, thank you so dearly for this video. You have just saved me so much money and heartache. You have a Sub for life. I will be ordering a kit tomorrow, when I get paid. How long should I expect it to take to get to Indiana?
Sure. I'm in Merrillville, to be exact, right off rt 30 and Madison. Walking distance from Meijer. Look me up on google under Titan Synthetics. Shoot me a text so I know when you're stopping by and I can get you a kit for $10 off (since I don't have to ship it).
So lets say the check valve breaks or hose pops out off the check valve or just any leak leaks in general around that modification they will loose break assist because they would have a major vacuum leak. Is there not a safer spot to t the vacuum from?
I’m a bit confused as to your question. I haven’t had any issues with leaks on thousands of these kits that have been shipped. I haven’t been using the T fitting on the v2 kit for years. The newest kit available is the v3.4 and it’s a completely different design.
@AndreiDPop lets say for instance the a side of the hose to the modified pcv comes off... now you have a vacuum leak and that t fitting you use to stack on top off the original vacuum for the brake booster is compromised and losing vacuum thus causing the brake assist to be minimized correct?
@@eduardopolvos9667 I don’t use a T fitting to stack on top of the brake booster. That design is no longer available and hasn’t been available for a few years now. Even so, that is a mechanically strong connection so at worst, you’d have a leak.
@@marion1600 awesome. Let me know if you have any other questions. If you don’t have the v3.4 pcv fix kit yet, it’s a great fix for this issue and great insurance against an expected failure and snowballed issues down the road.
Hey, good video. I came here from the cruze forum and had a question. You said to remove the old sealer between the timing cover and cylinder head and replace it with new sealer. What sealer did you use? Thanks
Actually, I personally don’t use any sealer. I shaved the timing cover gasket so it’s flush with the head and timing cover, and smoothed it flat with some sandpaper so it’s a perfectly flat surface. Haven’t needed any sealer there since. Been like that for about 70,000 miles.
My car’s vaccume regulator diaphrame is suking air. Not only this oil cap and dipstick also sucking air. What will be the problem? What i need to change?
It will contribute to one. It may not cause it on its own, but a P0299 isn’t indicative of one single failure, but rather a number of things that reduce the efficiency of the turbo system, so a small crack in the turbo may not trip a P0299, but a large crack would, or a small crack and a missing intake manifold check valve (the missing nipple). So even if the turbo has a small crack (very normal and develops within the first 1,000 miles), you may be able to get the P0299 code to go away by addressing the missing intake manifold check valve.
@AndreiDPop Yea the nipple is there On a tsb I found on Mitchell on demand it says to check the charge air bypass valve for oil water and sludge . I found that same oil and water Brown mixture all inside the PCV valve when I blew some air in there
@@tmangan327 the bypass valve solenoid will indeed also cause a p0299. It’s under the manifold on the passenger side. Worth noting that even having the check valve present won’t guarantee its working correctly. I recently had a customer with a 2015 encore with 96k miles on the car install my kit and pop his old check valve out, only to find that the flap surrounding the center hole has completely disintegrated and all that was left is the center. So that test isn’t even reliable anymore. Bypass valve solenoid sticking would cause vacuum to leak out to the bypass valve and cause the turbo to dump boost either intermittently or constantly. The condensation is from short trip driving, and the oil deposits are from running mediocre or sub-quality oil. I strongly recommend owners switch to AMSOIL signature series engine oil on these engines to prevent these kinds of issues.
Dan I have a 2013 Chevy Cruze 1.4T. I replaced he Valve cover due to Vacuum Regulator Diaphragm had suction on it. After I replaced it suction stooped but I noticed smoke and burning oil smell after driving it a few miles. I popped hood and oil was blowing out of oil filler cap. I checked the cap put a new Oring on but same thing> I put the oil valve cover on oil leak stopped but suction is back. Do you have any recommendations to my problem?
@@jamespuckett9572 we've seen a high rate of defect on aftermarket valve covers where there's an internal blockage that creates a ton of crankcase pressure.
The other day, my dad got this 0299 code on his 2014 encore but it was still driving fine. I ordered your turbo test kit but haven't had time to use it yet. Yesterday, he said the car wouldn't go up a hill, fell on its face and had no power whatsoever but didn't see the light come on again. Is it likely the turbo is shot at this point>?
Either turbo is gone or catalytic converter is clogged. This is assuming it’s not in limp mode which would clear up once the car gets shut off and on again.
I saw the nipple in the intake. If the debris is there can it still fail and cause to much pressure to build up in the crankcase and cause an oil leak????
what if you have oil coming out of the vacuum diaphragm on the top of the valve cover?i do not feel a vacuum leak at the little square port. it does smoke out of the tailpipe under acceleration. no check engine light or known driveability issues
Thanks for posting. I am a big fan of all your kits. I have purchased most of them. One question. What is the brass fitting with the nylon braided hose that looks to be installed on the passenger side of your cam cover with the hose going off screen on the drivers side? Thanks
So could a bad pvc pull a strong enough vacuum to get oil in the intake? I took my intake pipe off and it has oil in it and it's white smoking from the exhaust
Quick question, does the pcv hose at the intake manifold have both a rubber o ring and a black hard plastic washer or just the o ring? I disconnected it at the intake manifold but I can't seem to get it back on with a click/clip into place.
@@AndreiDPop Thanks. I just bought a replacement PCV hose because air is blowing through both ways on the old one. But the new one and it's replacement are also blowing both ways. If I blow hard enough there's some resistance but I thought they weren't supposed to do that.
Hello my GF just bought a 2014 Cruze and it has those problems I got a new cover ordered, I'm a dirt track race car mechanic stock cars and modified's, not a lot of experience with turbo engines. Question could I delete to pcv with a breather filter or no being a turbocharged engine?
This system I tested. Unfortunately for my daughter's car, her Cruze was pulling coolant into the #1 cylinder. I was hoping this was the answer but didn't fit all the symptoms. But very informative video.
@@mikewest8279 Her car wasn't overheating. It would only misfire for a few seconds after sitting for 30 minutes after driving. Unlikely though it was, classic head gasket symptoms. Pull the spark plugs and pressure test the cooling system. Or, cylinder leak pressure test and see if any air in the cooling system. Either way, the two shouldn't do that. That's a breach. Yours is more further along. My daughter traded her's for an Accord that same day.
Cannot thank you enough for walking through the various components of the PCV system. This allowed me to properly diagnose and repair the PCV system. It also saved me from spending additional money on the intake manifold that wasn’t needed…yet. I did need to run the car for quite a while (at least 30 minutes) after the repair to get all of the accumulated oil in the intake manifold driven out. I was overjoyed when the last bit of blue smoke stopped and the little engine got back to normal. She purrs like a kitten and pulls right up the hills better than she has for a while.
That’s so awesome to hear! Very glad that you were able to sue this information and get your car fixed. That’s been the goal behind everything I’ve done here. Saving people time, money, and frustration.
Hands down, Andrei creates the best DIY repair tutorials for the Chevy Cruze. His step-by-step instruction guides include pics, which virtually eliminates the need to take pics as you go along (although I recommend you do anyway). And his work-around kit for the POS OEM PCV system is ingenious and affordably priced. I feel like I owe him more money for making this so simple and affordable. Thanks, Andrei.
Thanks for the kind words and encouragement! You don't owe me a thing man, I'm glad you were able to use all of that info.
@@AndreiDPop to be fair, I just pulled the manifold yesterday. I will install the fix to it with your kit today. But what pain in the ass it was to pull the manifold!
Who is Andrei ?

I don't even own this car. I don't even know why I am watching this. But I learned a lot and I am a huge fan of the way you do videos. Very well done.
Hey, thanks for the feedback! It's very encouraging. I've been thinking I need to do more videos.
Thankfully you have found it necessary to share your great knowledge about this vehicle. Keep up the good work young man.
Hi
I spent countless hours trying stop the oil leak from around the valve cover. Saw your video, ordered the intake manifold and installed it. No more leaks!!! Thank you so much for taking the time to make the video. Truly helped. Now I’m searching how to remove oil stains from driveway..lol. Thanks again!!
This is one of the only videos on TH-cam that explains and fixes the problem correctly. I can't believe how many other video of "mechanics" not correctly fixing this problem. Thank you for all you have done for us fellow Cruze members. I will be buying your newest pcv fix kit. Thanks again
Man I wish more mechanics were as knowledgeable as you appear to be. Would have saved me loads of money over the years. I’ve found TH-cam and doing it yourself saves time and money and even the hassle. Thanks for sharing your knowledge. Subscribed and liked
I have been a Technician and do many other repair jobs for me and others. Save Soooooooo much money MOST of the time. Some time tools can be a "paywall", some times it's just a skill set you're not that good at. I don't do carpet or drywall; I will help do tile, not on my own. lol
Live and learn. Still, learn everything you can, and try anything!!
You are so great!!! A lot of people out there totally have no idea about that "vacum control membrane" and they call it PCV valve..
Actually i'm a physician but i have interest in automotive. I have 2008 chevrolet captiva and i dissasembly that "the so called pcv valve" and totally confuse about the name of "positive crankcase valve" becoz on that valve construction i bet it is not regulated by positive pressure, but the valve/membrane will actually move by negative pressure.
Then i found your video and you make it very clear that it actually a vacum control membrane!!! Thanks again 👍👍👍
Hi, thanks for inventing the kit. I just bought a 2011 Chevy Cruze Eco and ordered your kit already. I hope it works well because I want to make this car my daily driver.
Hi, could you give an update?
Thank you for having an explanation for this. I’ve been troubleshooting for months for a “squeaky noise” from my engine bay. Finally figured it out. Thank you again!
Glad to hear you figured it out!
That's a brilliant explanation, and your website explains it even better. I find it frustrating that mechanics don't think first about how these systems work, since understanding is necessary before one has any hope of fixing things properly. Matching blowby gas flow through a PCV with the dramatically variable intake vacuum of a turbo is a huge challenge. So, I guess we shouldn't be surprised this system is much more complex than a simple captive ball and spring.
Thanks 😊 I bought your kit and installed it and then changed the valve cover with the OEM one over a year ago and its still working great 👍
Great to hear! Thanks for reporting back!
45,000 miles, and now it's squealing like a pig. Glad this vid was here. Repairing this weekend.
241,000 miles on my cruze. I just had the water pump replaced today, 2nd time in doing this.... I'm hopeful it will keep going other 50,000 miles.
I'm getting a weird ticking sound when engine is running.... thoughts? Is that normal for this type of engine?
Same thing with myn but myn has 60000 mi
Dexter Morgan mine started with the ticking then started throwing this code 68k miles 2016
Just wanted to give a big shout out "Thank you!" as I had several codes - everything you'd mentioned in your video! I was on the fence about selling my 2014 Chevy Cruze LT and finding one error after another pop up, but since it's paid for, I thought why not see about fix it permanently? And so, I came across your video and purchased your "GM 1.4L LUV/LUJ PCV Fix Kit V2" - kind of a h*ly sh*t moment after firing it up and running it with your kit on! It now runs like it did when I drove it off the dealership parking lot! Wow - just wow! Dre Dan's kit was the perfect fix for all my problems so at the very least, I thought I'd write you and again, say thank you! For a 100% failure rated part, the intake manifold with it's cheaply designed check valve...well, this is the way! It was also a good time to clean the throttle body and everything I had access to - a lot of built up crud as this was the first time having it apart since I bought it. This was surprisingly an easy job and your kit came with everything you need - was fun actually! Dre Dan, so glad I purchased your kit!
Thanks for the awesome review! I really appreciate it. I'm so glad this fixed your issue. It's great seeing feedback like yours. I really appreciate it!
Compliments on a perfect tutorial ... theory and practice.
Thank you Dre Dan! I was leaking oil from the throttle body on 2012 cruze lt. Didn't see a nipple after removing corrugated hose. Sure enough the orange check valve was missing after taking the intake manifold off. Huuuge thanks for all the info on cruzetalk and here.
Ya my 2015 cruze lt is leaking oil from the intercooler charge pipe connected to the throttle body, i was wondering if i shoukd take the manifold off and take a look but its my everyday car so its abit hard to check at the moment
how long did the intake manifold take to remove and replace
Thank you, you just save me over $500 my encore has hissing so it’s only value cover replacement, greatly appreciate you posting this video and I will buy that kit you make if manifold ever fails.
Keep in mind, simply seeing the check valve in the intake manifold doesn't mean it's working. Very recently, I had a friend install my kit which meant pushing the check valve out and catching it on the other side to plug it up with my kit. Turns out his had a tear in it, and it wasn't during removal. For many people, the check valve either gets stuck closed or even caked with deposits and starts leaking. Waiting for it to fail can often cause other issues down the road due to oil consumption. If you have over 30k miles on the intake manifold, I recommend not waiting until it fails.
@@AndreiDPop Well, I have only changed the intake manifold once on my Cruze and I have 306,464 miles now. The valve cover has been changed 3 times. But sadly my turbocharger is starting to fail. Wastegate is locking up. This is the original turbo and has lasted over 300,000 miles.
@@dextermorgan5799 That must be a lot of highway driving. Kind of need to go by years when you drive that much.
@@AndreiDPop Bingo! I would say 90% of the miles are highway driving. Drive over 30,000 miles a year. I have owned the car since January 2011. I've been good to this car and I think I got my money's worth. One last note, I never used air conditioning, no matter how hot it was. It seemed to affect the car early on. So, I decided to not use it.
@@AndreiDPop "Keep in mind, simply seeing the check valve in the intake manifold doesn't mean it's working." ... - This point cannot be stressed enough. I'm from the UK & work primarily on Vauxhall, a brand of GM, using the same systems; all are terribly designed. The intake manifold PCV non-return / check valves can indeed tear or become clogged "open" with carbonised / burnt oil deposits; symptoms are mainly observable with positive manifold pressure, ie. "boost". Faults with this valve will cause consequential faults with many other components.
Nice video. I really never wanted to learn about the PCV system but I guess it's my time.
If you own a Cruze, your time will come, sooner than later. It is a 100-percent certainty.
you're hilarious! 😂
My time came yesterday
Amazing info, just replaced that valve cover in my automotive class
finally the info I needed. Thank you sir!
Best description so far. Concise.
Thanks!
Thank you this video has saving me so much!
you explained that as well as anyone ive seen thanks.. im need to do the bypass kit so ill be ordering it soon
Excellent informative vid, just shit that the valves are part of large expensive components.
Thanks for the help so I can tell my mechanic I did research on these Pcv valves cause I had a really bad rough idle even after cleaning the throttle body with no codes unfortunately I checked the Pcv valve in the intake manifold and it’s all gunked up can’t even see where the nipple is so I’m gonna have him replace that with the Pcv valve cover as well and hopefully that fixes it. Just taking extra precautions and having home fix those even after the diagnosis and whatever else he finds needs to be replaced or repaired.
Your video talked about the other end of the PCV hose at the turbo and a check valve there. Does that one go bad and ever need replaced?
Next question:
If the valve cover gasket goes bad, does this create a vacuum leak and cause poor performance?
My Cruze gets random lifter noise that comes and goes. I checked the valve on the valve cover, but it wasn't blowing air. I replaced the valve cover gasket because it was leaking oil. Since then, I've had no issues.
Yes, the check valve on the other end of the PCV hose sometimes goes bad, and creates a vacuum leak. We find it gets stuck open more than it does get stuck closed.
Yes, a bad valve cover gasket can cause a vacuum leak.
Check spark plugs, as they sometimes back out. Lifters shouldn't make any noise unless you've been using low quality oil.
Nice bypass filter system, is it Amsoil? I put one on my 2.4l Ecotec. It returns directly onto the timing chain, keeping it bathed in clean oil, no more GDI soot. I also did an external PCV system. After 100k miles, engine is extremely clean, no varnish, sludge, even 10-12k intervals.
Yes it’s an AMSOIL single remote bypass. Not really much benefit outside of adding an extra quart of oil capacity but it was a fun project. I took it off last year after using it for 8 years due to the cost of filter changes.
@AndreiDPop really, no benefit? How do you come to that conclusion. Being an Amsoil dealer, I thought you would understand the benefit. I stopped using PI, Engine Flush, Power Foam, did nothing to help. Still use Metal Protector.
@@tssci6774 soot and insoluble contamination isn’t a concern with gasoline engines. That’s why you only ever see bypass filters where soot levels are measurable. I ran a case study with AMSOIL in a focus ST where we did 13 oil analysis reports and 50,000 miles on two EAO filters. Lab said oil was suitable for continued use and there was no soot measured.
I did another case study with a Cruze turbo diesel that went 100k miles on AMSOIL AEL and soot wasn’t an issue with that engine either.
So if soot isn’t an issue and wear is at acceptable rates, what benefit is the bypass filter offering? On paper yes I could say beta75 at 2 microns is great filtration but at the end of the day is it consequential? In my opinion it isn’t.
I heard this today. "Vehicles nowadays can surf the web, stream videos, navigate and pinpoint a location in a map, but can't tell you why their check engine light is on." How ironic is that?
I would say, "Todays cars do so many gee-wizzy things but are not reliable transportation".

Best mechanic video I've ever watched
Thank you so much for this video and your kit! I will buying one ASAP!
Impressive! Very detailed and educational. Phenomenal job!
Hello, and thanks much for this video and the kit you've designed... i will likely be ordering one of those shortly.
My girlfriend has a Cruze, and the diaphragm on the valve cover is indeed failed and leaking vacuum.... it also sometimes makes a whostling sound that sounds like a belt squeal... when you plug the vent of the diaphragm on the valce cover it immediately makes this sound. I've diagnosed this to be vacuum leaking , and sucking air in around the crank seal.
I am thinking that adding your kit, as well as a new valve cover, and possibly the hose and valve by the turbo inlet, will ALL be necessary, but I also think we should be replacing the crank seal as well....she will likely keep the car, or eventually give it to one of her kids , so I want to fix it right...
Any further input or suggestions would be most appreciated. Thanks again for doing us all the service of making this video, and designing a kit to provide a metter solution than OEM part replacement....
Even after all that, you really think this thing will last? Haven't talked to or seen anyone saying these are cars that can be depended on to last without giant headaches every few years
I had same issue with a sonic. only when i covered the diaphragm hole it started directing oil into the intake and then the car started smoking from the tailpipe like crazy. Thanks for the info will be ordering kits from you.
Dear Dre Dan,
Thanks for your great videos, explanation and kits avaliable to get - it's great solution for this strange crankcase ventilation system from GM with this PCV Mushroom valve in the intake manifold at A14NET engine and similar. I wonder to know, why they don't use the same system which used at A16LET engine, where the PCV valve made externally, almost exactly how you made at your kits? It's rhetoric question ;)
But what I really wonder to know and can't find relevant information concerning this issue - what if the ventilation system will only one way. I mean, if the mushroom valve hole will be plugged up in the intake manifold and only way of ventilation will be via corrugated hose to the the turbo charger. Such way will be completely identical to the default ventilation system during the boosted, loaded mode. But what will happen at the idle mode or mode with little load ? I suppose, that if it will be not enough air at the intake manifold for the stable engine operation the electronics will open the throttle valve a bit more to provide the enough air flow. Further the more air will be sucked from the turbo charger and from the corrugated hose connected to turbo inlet - so the crankcase ventilation will take place in this case as well.
I am not completely confident in my thoughts concerning this crankcase ventilation as I am not specialist in it, but why double-way ventilation system needed, what is the benefit of it?
Best,
Igor
Wow thank you Igor. You just gave a great explanation of what is most likely going on with my vehicle. Now just need to buy a kit and see if I can find the root of the problem. Thank you man
@@franklujan7480 Hey Frank - btw I don't own Astra anymore, but I was able to fix it with the way described with "self-made kit" and after fix had another ~20k km successfully. Best of luck!
Your description was text book. Had a problem that cost me a good chunk of change. I wish i had seen this video ages ago
Dre Dan, Thanks for the video! Great explanation on the system. I have an oil leak somewhere between the charge line and throttlebody. Have you heard of this before?
Yes. This is typically made worse by a missing check valve in the intake manifold, but otherwise simply means the clamp isn't tight enough.
@@AndreiDPop Am I reading this correctly? Are you implying that some oil leaking from the charge pipe is acceptable? A lose clamp? Wouldnt this be a check valve issue, resolved with a DRY charge pipe yes?
@@ripptydevibes2581 If you have oil leaking form the charge pipe, you also have a boost leak there as well. Some oil will come through the PCV system, but it tends to settle in front of the throttle body and leak at that charge pipe, even if actual consumption is inconsequential. Even a healthy car will consume some oil through the PCV system, and some of that will find its way through the intercooler and up the charge pipes. Not something to worry about unless oil consumption increases significantly. A check valve issue will make it *worse* but a minor amount of oil will still go through the charge pipe on a healthy engine.
@@AndreiDPop Agreed, thanks for the quick reply. I guess we arent as used to seeing oil at the intake on natural aspiration, but owning my 98 mitsu 2.0l running 32psi, it was nice of you to remind me that it is somewhat normal for the Chevy Cruze to have oil in its charge pipe lol. This customer is missing the check valve nipple, and im considering pricing your deletion kit and valve cover job, but shes already been in deep with this cruze at 100k miles so im almost as likely to start washing my hands of it and let someone else grow into the bad guy lol. Shes complaining of the heater vent smells and ive already rerouted her coolant breather to under the frame, gonna tell her take it to chevy for that but then theyre gonna hammer her with a list of reasons and $2000 in repairs that likely wont do anything! Thanks again!!
@@ripptydevibes2581 the v2.1 kit should keep her PCV problems at bay. It's not a deletion kit but a re-route with serviceable components. I also have installer pricing at 15% off if you want to go this route.

Hey buddy, I recently installed a new intake manifold and valve cover before finding your kit, could you possibly explain too me where the bypass hose coming from the turbo is connected too? Specifically on the engine side? I have mine connected where the turbo is but I can’t for the life of me find out where the other end goes ( I believe this is creating another vacuum leak) that being said if this fails again (which is likely) I will be purchasing your kit. Thank you!
Literally I was looking at the broken end of that corrugated hose in my hand thinking "wow that was smart" and in my Bluetooth headset I hear "now be careful just gets brittle over time". F this day.
Better for it to crack now so you know to replace it than for it to happen down the road and you have no clue why it's not running right.

it was a bad concept and design.
Currently working to be ridd of my 2015 Cruz LT, less than 97,400 miles and still under warranty but constantly denied any warranty coverage. Also, learned yesterday when the mechanic was on the phone with the warranty department, this car was sold to me without informing me of the recall that is ongoing. It's sitting in my driveway after being towed home yesterday because I refuse to sink another penny in this money pit. As of last week, I've had the pos 20 months; its broke down a 4th time. And this time, the issue is the same as the first time it broke down. JUNK!
I let them repo my 2012 back in 2014 ROFL. Stupid little short car.
what is the other hose that's tapped into the valve cover opposite side of the oil fill cap? also are you not running the factory style coil anymore? i see you have 4 sperate spark plug cables there.
@@brandoncatanzarite8729 that’s an AMSOIL single remote bypass filter return line.
I’m running badnewsracing.net LS7 coils to support the badnewsracing upgraded GTX turbo.
So, basically GM is still building junk.
Pretty much. Fortunately, these cars drive pretty well, and all of the issues are pretty simple and cheap to resolve.
Dre Dan As opposed to my new 17 Civic, the new Cruze has five more inches of leg room, better seat angles and comfort, less road noise, more torque, better styling, and music/infotainment/sat radio. But, its the reliability and clutch engagement that concerned me. I wish I had the Cruze for the comfort. You cant have it all.
Can an issue left unresolved in the intake manifold cause issues with the diaphragm?
I’d previously replaced the diaphragm when my check engine light had come and I felt the vacuum issue out of the diaphragm hole on the valve cover, but only recently installed your v3.4 pcv fix kit when I was starting to have rpm issues idling and those issues are persisting even after your kit was installed, though no check engine light yet
Yes and it happens often. With the intake manifold malfunctioning or failing, the valve cover will fail prematurely, even 5x more often.
Sounds like you have a vacuum leak, so you’ll need to find and address that.
Do you have another video on how to put your kit and how to purchase it.I also have a 2012 cruze and the orange nipple is gone and that has to be the problem of the car shaking like it has a vacuum problem.
There’s a video for the v3 install and there’s downloadable paper instructions on the cruzekits site for the v1 and v2.1.
Most people order the newest v3.4 kit as that’s the easiest to install. Be sure to read the note sheet!
I just used the boost leak test kit. The only leak I had was throught the valve cover gasket. Could that be because the PCV it shot? I have a sonic I can't look down the PCV hose inlet.
Nvm. Got it. You rock btw. Kit worked amazing
Thanks for posting this. I have a 2013 Volt, which has the same engine just without the turbo. It wouldn't pass emissions nor would it set a check engine light. It was running just lean enough to not set O2 sensor readiness nor was it lean enough to set a check engine light because of the same exact leak in the valve cover.
With the kit installed, is it necessary to add an oil catch can to the system as well if you have a build motor an v3 turbo upgrade?!
With the kit installed, you should need a catch can at all. However, the v3 turbo may create conditions that create a need for a catch can so I can't say if you'll need one then.
Okay thank you, I’ll order one an still get the catch can because I’m looking to make Bigg power, thanks again for your response!
@@paceauto5382 make a note in the kit when you order it so I can get you the T fitting you'll need for the catch can setup. The fitting currently used wouldn't be very good for adding a catch can.

@@brannontejeda3854 it will cause more oil to come in, yes. If that valve is bad, you should install the cruzekits pcv fix kit ASAP.
So if I'm getting suction from that diaphragm on top and also don't have a nipple for the check valve, do I need to replace/repair both?.....I've also got a bad front crankshaft seal that I'll have to replace due to the squeaking noise.

Please reply, it's urgent.
Ive had the kit V3 kit on my 2014 Cruze 1.4 for about over a month or so. Have not had any issues. The crank pulley whistle, the PCV air inlet suction, rough idling, hesitation, check engine light, all have gone away and have not come back once. I did not replace the valve cover, I did not replace the intake manifold.
Is your check valve on the v3 kit pointing in the correct direction?
@@AndreiDPop Yes, and there are no problems. I was adding another testimony to what a good solution this is.
Does that corrugated tube have a barb on the end cause was wondering if you could just replace that with a normal rubber line and put a inline check valve in cause I did something similar on a vxr for a hard brake booster line using stronger vacuum rubber lines of course saves me from drilling the intake manifold
what you’re trying to do won’t work at all. Yes it has a barbed end and he’s you can use a PCV hose but no you can’t just run any inline check valve anywhere and especially not in the 5/8 line because there’s already one there. The v3.4 pcv fix kit does not require drilling or removal of the intake manifold.
@@AndreiDPop ok thanks for the reply and fixing my error will just get the new kit then
I wiped out the area but there's no round orange tip but there's something raised up but looks like flat and black in color. It's hard to tell without taking the intake out. Is that check valve round or flat? I am getting P0299, the car is under power, the line/hose from intake to turbo has some oil and my air intake connection at the line coming from intercooler is soaked with oil. I am trying to figure out the problem before replacing parts. I just installed a brand new Chevy valve cover.
Your check valve is gone. You need to install one of my pcv fix kits. That should address your p0299 and restore some power and fuel economy and reduce the oil consumption.
@@AndreiDPop Sounds good! Thanks
Is the valve cover gasket replaceable? Fixed a p0299 with a clip missing of the wastegate/disconnected. Now I have an oil leak. Replace the big hose with the two check valves because it broke when checking the little valve in the intake. Any thoughts would be great if you have the time. The oil leak wasn’t present prior to fixing the turbo clip. Thanks in advance.
My 19 Cruze LS has 30.6K. A perfect car with zero issues.
Hello Dre Dan, i have a strange noise in my opel corsa with 1.4 turbo motor from 2014(its the same motor as in the cruze), when its warm an its no belt driven part - i checked it without the belt. I checked the PCV valve to the turbo, its switching when i blow in an suck there and i can see the nipple in the intake and the valve cover isnt sucking air. But i have the simmer ring squeeking when i shut off the engine and a noise like a sqeaking belt when its warm. Is it possible to have a higher underpressure on the enginge caused by the valve cover? I first want to change the simmerring but if its not the solution for it i maybe want to change the valve cover. What do you think? The next step could be an expensive change of the timing chain. Sorry for my bad english ;)
16 Encore.. Was getting a Underboost code for a while, and i had an oil leak at the oil filter housing.. I replaced the Housing plus the turbo and now the car is misfiring and blowing white smoke.. what could this be?
So the other hose in the valve cover is the same for the pcv function? And whatbof the product donu recommended for my sonic rs 1.4 please . Thanks
That hose in m valve cover is a return line for my AMSOIL bypass filter.
So what tipe of the kits do u recomend for my sonic rs 1.4 is stock engine
@@sancheztorres35 the most popular, easiest to install, and best value is the v3.4 kit. That should be your best bet.
Mine looks like yours, when you buy replacement valve cover it shows on the paper that part of the manifold but the circles around have orange. Ours only have the center nipple. Wouldn’t that be an issue as well ?
You can only see the orange around the circles when looking in from the end of the runners not from the top where the pcv pipe goes.
Hey man, i aciddently broke the one tube connecting to the valve. Should i get a replacement or can i tape it up good and it should be fine?
Dr dan im having a underboost p0299 code noticed oil on front of cylinder head u have any idea u think im having a pvc issue sir were should i start
Inspect the intake manifold for the missing check valve.
@@AndreiDPop thank u sir much appriciated i had guy giving me the run around wanted me to change coil packs boost sensors but i kbow thats not the issue theres backpressure creating somewere for the oil to be seeping threw the front head gasket pvc issue again im going to check thank u sir
Would this problem result in coolant leak anywhere? Trying to determine if I'm having a head gasket problem. Thank you!
I have what seems to be an engine oil leak on the right of the engine, coming from the lower hose by the temp housing unit. I also notice that one of the torque screws on my valve cover is constantly dirtier than the rest. This is the one on the front left of the valve cover. What can this mean? Basically my 1.4 turbo isnt producing enough power to run my AC on hot days. The AC works fine, but after 20 mins of running the car sometimes doesnt start up. Any ideas of leads of what I should check? thank you!
Barry Zelcer is the leak related to turbocharger oil lines? those have updated parts
So it is normal air suction through oil cap when is in idle? My intake manifold has the orange nipple and new valve cover, i still have some suction through oil cap, car runs good no check engine lights , just wondering if is norma air suction???
Yes, that’s normal.
Hi Dre Dan. I just bought a sonic with 1.4l turbo. The vacuum regulator is leaking oil from there. Do you think it has to do with the pcv valves? Any help, I'll priciate.
@@aldonoviaviles6250 you’ll need a new OEM valve cover. You can get those from the dealer but I also offer them on the cruzekits.com site. Have you checked the intake manifold yet?
@AndreiDPop so I have replaced all ready the valve cover with zzperformence. The old one was bad due to an air leak at the regulator. After a put the new one 2 weeks later, I noticed that it is leaking oil. I call the zzperfomence for the warranty and they are tell me that it couldn't be the the regulator. And I haven't check the intake manifold yet. Can you send a link to the repair kit?
@@aldonoviaviles6250 if it’s leaking oil, it’s defective. Nothing else to it.
Cruzekits.com has the pcv fix kit and the OEM valve cover.
@AndreiDPop I appreciate your time, and soon I will order the vulve kit. Thank you again. You're a humble person.
Will your PCV kit extend the life of the vacuum regulator diaphragm in the crank case cover / i.e. does a missing PCV in the intake manifold damage the diaphragm? I'm at about 98,000 miles and I'm on my 3rd crank case cover. I just installed your V3 kit and the car seems to be running well. When I give it gas, it no longer hesitates - i.e. feels like more acceleration power. So far .. so good.
In my observation and experience, yes. I've had reports of people replacing 8 valve covers over a 2-year period, not realizing that their intake manifold check valve went bad. Others would install my pcv fix kit and get over 65k miles on a single valve cover.
I think what's happening is that the missing intake manifold check valve introduces such a high volume of boost into the PCV system that, combined with the blow gas produced by the engine, exceeds the flow capacity of the turbo side pcv pipe check valve and pressurizes the crankcase as a result. This then causes the diaphragm in the valve cover to flex in the opposite direction than it was designed to, which causes premature failure over time.
Maintaining a healthy PCV system would then resolve this issue, and the valve cover would only fail in the event that the diaphragm becomes brittle enough due to normal operation that it cracks on its own.
Your experience is consistent with others that have had this issue, reporting better power and no more hesitation. You should also notice an increase in fuel economy.
@@AndreiDPop that's good news. I'm on my 3rd valve cover - replaced it 2 days ago and installed your V3 kit earlier today after it arrived in the mail. I definitely notice a difference when I took it on it's first drive. The dealership replaced the cover the 1st time, then about a year after that, the turbo charger failed and had to be replaced - thankfully it was still covered under the drive train warrantee. Could the missing PCV have played a role in the Turbo Charger failure?
Question: if the PCV valve inside the intake manifold fails, will this cause a turbocharger failure?
@@sandrahodson no, but it can cause a p0299 code.
Thanks for your response. I have a 2015 Buick Encore with the 1.4 L turbo. My turbo went out with the P0299 code. It took three replacements to correct the problem. The first two broke again . I was told the intake manifold needed to be replaced due to a clogged PCV, and that's why the turbos kept failing. I asked them to replace the valve cover and PCV hose at the same time (Dorman kit). I know you offer a fix kit on your website also. I no sooner left the shop after repairs, when the CEL was back again with a P0420 code. Ugh!! They did an eval and now said the catalytic converter is bad. What is the likelihood of that occurring right after the other repairs were done? The car seems to be running fine. If I clear the code, I can drive for hours at high speeds on the freeway without the CEL reappearing. It comes back with city driving. Why? @@AndreiDPop
@@sandrahodson the failure of the intake manifold check valve causes excess oil consumption, which poisons the catalytic converter over time.
Would this cause white smoke out the exhaust as well? I've got the p0171 p0106 p1101 codes and the disc thing on top of the valve cover is indeed sucking air and I cant see the orange nipple in the intake manifold. I wasn't concerned about it until I noticed it's white smoking but it doesn't smell like oil or coolant. Just smells like regular exhaust fumes but is thick white clouds when first starting up then it eases off a little.
Hello I have a Opel Corsa E 1.4T theres 3 different kits on your site which one is the correct one?
The Dr is in!! My man, thank you so dearly for this video. You have just saved me so much money and heartache. You have a Sub for life. I will be ordering a kit tomorrow, when I get paid. How long should I expect it to take to get to Indiana?
Well I'm in Indiana (NW side near Chicago), so realistically, one or two business days.
@@AndreiDPop No way! I live in Valpo and work in Hammond! Is it possible to meet up this weekend?
I normally wouldn't ask, but I have to drive this car to Detroit on Sunday night.
Sure. I'm in Merrillville, to be exact, right off rt 30 and Madison. Walking distance from Meijer. Look me up on google under Titan Synthetics. Shoot me a text so I know when you're stopping by and I can get you a kit for $10 off (since I don't have to ship it).
@@AndreiDPop You are officially my new best friend! I can be there tomorrow at 4:15 sharp!
So lets say the check valve breaks or hose pops out off the check valve or just any leak leaks in general around that modification they will loose break assist because they would have a major vacuum leak. Is there not a safer spot to t the vacuum from?
I’m a bit confused as to your question. I haven’t had any issues with leaks on thousands of these kits that have been shipped. I haven’t been using the T fitting on the v2 kit for years. The newest kit available is the v3.4 and it’s a completely different design.
@AndreiDPop lets say for instance the a side of the hose to the modified pcv comes off... now you have a vacuum leak and that t fitting you use to stack on top off the original vacuum for the brake booster is compromised and losing vacuum thus causing the brake assist to be minimized correct?
@@eduardopolvos9667 I don’t use a T fitting to stack on top of the brake booster. That design is no longer available and hasn’t been available for a few years now.
Even so, that is a mechanically strong connection so at worst, you’d have a leak.
Wow that was a really thorough video thanks. Even provided a custom fix.
Very good explanation but I don't see what prevents boost going to the turbo inlet
The intake manifold check valve prevents boost from going into the turbo inlet, if it’s still there and if it’s working correctly.
@@AndreiDPop I watched again and yes I got it now. Thank you!
@@marion1600 awesome. Let me know if you have any other questions.
If you don’t have the v3.4 pcv fix kit yet, it’s a great fix for this issue and great insurance against an expected failure and snowballed issues down the road.
This is super helpful. Thank you for making this.
Hey, good video. I came here from the cruze forum and had a question. You said to remove the old sealer between the timing cover and cylinder head and replace it with new sealer. What sealer did you use? Thanks
Actually, I personally don’t use any sealer. I shaved the timing cover gasket so it’s flush with the head and timing cover, and smoothed it flat with some sandpaper so it’s a perfectly flat surface. Haven’t needed any sealer there since. Been like that for about 70,000 miles.
What is the aftermarket Hose coming off the top of your valve cover...
AMSOIL single remote bypass oil filter return line.
My car’s vaccume regulator diaphrame is suking air. Not only this oil cap and dipstick also sucking air. What will be the problem? What i need to change?
New OEM valve cover first. Check for missing intake manifold check valve.
If that nipple you're talking about inside the intake is missing will that cause the p0299 under boost code ?
It will contribute to one. It may not cause it on its own, but a P0299 isn’t indicative of one single failure, but rather a number of things that reduce the efficiency of the turbo system, so a small crack in the turbo may not trip a P0299, but a large crack would, or a small crack and a missing intake manifold check valve (the missing nipple). So even if the turbo has a small crack (very normal and develops within the first 1,000 miles), you may be able to get the P0299 code to go away by addressing the missing intake manifold check valve.
The oil cap was left off and vehicle was driven around for about 20- 30 min ever since then the po299 code came on
@@tmangan327 that shouldn’t cause an oil cap to be off on its own. That would have been a p0171. Have you checked the intake manifold yet?
@AndreiDPop
Yea the nipple is there
On a tsb I found on Mitchell on demand it says to check the charge air bypass valve for oil water and sludge . I found that same oil and water Brown mixture all inside the PCV valve when I blew some air in there
@@tmangan327 the bypass valve solenoid will indeed also cause a p0299. It’s under the manifold on the passenger side.
Worth noting that even having the check valve present won’t guarantee its working correctly. I recently had a customer with a 2015 encore with 96k miles on the car install my kit and pop his old check valve out, only to find that the flap surrounding the center hole has completely disintegrated and all that was left is the center. So that test isn’t even reliable anymore.
Bypass valve solenoid sticking would cause vacuum to leak out to the bypass valve and cause the turbo to dump boost either intermittently or constantly.
The condensation is from short trip driving, and the oil deposits are from running mediocre or sub-quality oil.
I strongly recommend owners switch to AMSOIL signature series engine oil on these engines to prevent these kinds of issues.
Dan I have a 2013 Chevy Cruze 1.4T. I replaced he Valve cover due to Vacuum Regulator Diaphragm had suction on it. After I replaced it suction stooped but I noticed smoke and burning oil smell after driving it a few miles. I popped hood and oil was blowing out of oil filler cap. I checked the cap put a new Oring on but same thing> I put the oil valve cover on oil leak stopped but suction is back. Do you have any recommendations to my problem?
OEM or aftermarket valve cover?
How's the check valve in the intake manifold?
Aftermarket
Need to check the check valve
@@jamespuckett9572 we've seen a high rate of defect on aftermarket valve covers where there's an internal blockage that creates a ton of crankcase pressure.
So I will check the check valve then see about getting your part
Does the second pcv check valve located inside the tube itself or in the turbo?
@@סהרקדמי in the terminal of the pcv pipe. In the end connector.
The other day, my dad got this 0299 code on his 2014 encore but it was still driving fine. I ordered your turbo test kit but haven't had time to use it yet. Yesterday, he said the car wouldn't go up a hill, fell on its face and had no power whatsoever but didn't see the light come on again. Is it likely the turbo is shot at this point>?
Either turbo is gone or catalytic converter is clogged. This is assuming it’s not in limp mode which would clear up once the car gets shut off and on again.
@@AndreiDPop Thanks for the response. Any quick way to differentiate between the 2 issues?
I saw the nipple in the intake. If the debris is there can it still fail and cause to much pressure to build up in the crankcase and cause an oil leak????
what if you have oil coming out of the vacuum diaphragm on the top of the valve cover?i do not feel a vacuum leak at the little square port. it does smoke out of the tailpipe under acceleration.
no check engine light or known driveability issues
vincent zuhowsky piston ring failure?
Thanks for posting. I am a big fan of all your kits. I have purchased most of them. One question. What is the brass fitting with the nylon braided hose that looks to be installed on the passenger side of your cam cover with the hose going off screen on the drivers side? Thanks
Thanks for the reply! It's a return line for my AMSOIL single remote bypass filter.
Dre Dan we cant wait to see that how to video! Thanks again!
So could a bad pvc pull a strong enough vacuum to get oil in the intake? I took my intake pipe off and it has oil in it and it's white smoking from the exhaust
No that would probably be a bad valve cover. Intake manifold could have caused that so you’ll want to check both.
@@AndreiDPop well I just bought your pcv kit. I hope it solves my problems 😅👍
Quick question, does the pcv hose at the intake manifold have both a rubber o ring and a black hard plastic washer or just the o ring? I disconnected it at the intake manifold but I can't seem to get it back on with a click/clip into place.
Yes it has both. Get some grease on the manifold and it will go back on.
@@AndreiDPop Thanks. I just bought a replacement PCV hose because air is blowing through both ways on the old one. But the new one and it's replacement are also blowing both ways. If I blow hard enough there's some resistance but I thought they weren't supposed to do that.
Figured out that the inexpensive ones don't work like the genuine oem replacement. But now the Diaphragm is sucking in air hard... UGH.
@@FrankWithanF get a new valve cover on there asap
@@AndreiDPop for anyone reading this. The dealership fixed it for free because a special coverage.
Hello my GF just bought a 2014 Cruze and it has those problems I got a new cover ordered, I'm a dirt track race car mechanic stock cars and modified's, not a lot of experience with turbo engines. Question could I delete to pcv with a breather filter or no being a turbocharged engine?
This system I tested. Unfortunately for my daughter's car, her Cruze was pulling coolant into the #1 cylinder. I was hoping this was the answer but didn't fit all the symptoms. But very informative video.
mike vonkleist how do you troubleshoot that? Have a feeling ours is doing the same, losing coolant to and runs hot
@@mikewest8279 Her car wasn't overheating. It would only misfire for a few seconds after sitting for 30 minutes after driving. Unlikely though it was, classic head gasket symptoms. Pull the spark plugs and pressure test the cooling system. Or, cylinder leak pressure test and see if any air in the cooling system. Either way, the two shouldn't do that. That's a breach. Yours is more further along. My daughter traded her's for an Accord that same day.
